[BDW GT3] Backport fixes to unbreak X

Hello Timo, or anyone else affected,

Accepted xserver-xorg-video-intel into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/xserver-xorg-video-intel/2:2.99.910-0ubuntu1.5 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Status changed to 'Confirmed' because the bug affects multiple users.

Dear raof,

Is it possible to force install this new package from trusty-proposed without updating other X.org stuff related packages?

Thanks

Dear All as #3 said is there anyway to get this fix to trusty tahr? that would be really great. thank you

@girisha: if you're OK to have last packages from proposed-updates you may follow instructions on https://wiki.ubuntu.com/Testing/EnableProposed to easily test the new package.

In my case I just realize that I had previously upgraded to Utopic graphics stack so my curent package is xserver-xorg-video-intel-lts-utopic (2:2.99.914-1~exp1ubuntu4.2~trusty1) and no more xserver-xorg-video-intel (2:2.99.910-0ubuntu1.4).

If anybody with trusty original's graphic stack can test the new package (ubuntu1.5) (maybe trying to force ut with dpkg, if you don't want to enable all proposed-updates, but at your own risks).

Also if a new xserver-xorg-video-intel-lts-utopic proposed package is release I will try it on my system as descrive above.

installing just this package doesn't pull any extra ones

At least I does on my config:
apt-get install xserver-xorg-video-intel/trusty-proposed -s
[snip]
l'information suivante devrait vous aider à résoudre la situation :

Les paquets suivants contiennent des dépendances non satisfaites :
 xserver-xorg-video-intel : Dépend: xorg-video-abi-15
                            Dépend: xserver-xorg-core (>= 2:1.14.99.902)
E: Impossible de corriger les problèmes, des paquets défectueux sont en mode « garder en l'état ».

well the package is meant for the stock trusty install, not 14.04.2 with utopic stack (*-lts-utopic)

That' right : should it be possible to produce the package for utopic stack under Trusty ? I would be happy to test it.

sudo apt-get install xserver-xorg-video-intel/trusty-proposed -s
on xorg-video-abi-15 leads to:

Confirmed bug on Lenovo E550.
Prominently appears when plugging in an external Samsung S23C350 screen before boot/power on however plugging it in once logged it. Thus far the bug has only once occurred when the external screen is not plugged in.

https://bugs.launchpad.net/linux/+bug/1432194 :: bug #1432194 refers to the same/similar issue.

The fix mentioned has not fixed my installation using xserver-xorg-video-intel-lts-utopic ver 2.99.914-1 (Comment #8 mentions that fix is not for utopic - possibly why the fix did not work)

@ #12 at the time of commenting the proposed fixed is yet to be pushed on trusty proposed.. I guess we will have to wait a few hours :)

lihow731 tested the trusty package

Status changed to 'Confirmed' because the bug affects multiple users.

as mentioned above I enabled trusty proposed updates and then created the proposed-updates file in /etc/apt/preferences.d

Package: *
Pin: release a=trusty-proposed
Pin-Priority: 400

so far I have not seen the update on trusty 14.04 (3.16.0-34-generic #47~14.04.1-Ubuntu)

Because there is no fix uploaded for utopic yet. After that's in utopic-proposed and tested, the backport for trusty can be created..

you can't test the stock trusty package version on lts backport stack, as has been pointed out many times by now

@ #17

Dear Timo, Thank you for the response. I was unaware of the terminology and how the bug fix is pushed. Sorry!!

As a workaround for utopic graphic stack users in trusty, I'm looking for a good way to revert back to the stock trusty package to use the proposed package, so if anybody try it, please share :)

*** dirty temp workaround for hurry people ***
If you want to use SNA on Ubuntu 14.04 with lts enablement stack while waiting for the patched xserver-xorg-video-intel-lts-utopic package, you may just replace the following files with the same files coming from the xserver-xorg-video-intel ([1] or [2]) package in trusty-proposed version (do it in tty1 for example as you will replace in use driver! ):
/usr/lib/libI810XvMC.so.1.0.0
/usr/lib/libIntelXvMC.so.1.0.0
/usr/lib/xorg/modules/drivers/intel_drv.so

Don't forget to remove any conf file you may have added to use XNA in /etc/X11/xorg.conf.d/.

This is really dirty, I don't know what will happen when the official package will come (don't forget to backup original files), but at least it seems to work for me !

[1] amd64 : http://fr.archive.ubuntu.com/ubuntu/pool/main/x/xserver-xorg-video-intel/xserver-xorg-video-intel-dbg_2.99.910-0ubuntu1.6_amd64.deb
[2] i386 : http://fr.archive.ubuntu.com/ubuntu/pool/main/x/xserver-xorg-video-intel/xserver-xorg-video-intel-dbg_2.99.910-0ubuntu1.6_i386.deb

no, it really shouldn't work, since it's not built against the lts stack xserver..

Is updating to 15.04 a solution?

You right, it doesn't work, and X load "Gallium 0.4 on llvmpipe (LLVM 3.5, 256 bits)" as intel driver is of course not OK.

the utopic & lts-utopic packages have been uploaded but not accepted yet

the fix got acked and is building now, should be in utopic-proposed soon (and the backport for trusty too)

 -- Timo Aaltonen <email address hidden> Wed, 22 Apr 2015 19:57:12 +0300

Unfortunately, the proposed package don't fix my problem.

I install the proposed package :

dpkg -l | grep video-intel | grep ii$
ii xserver-xorg-video-intel-lts-utopic 2:2.99.914-1~exp1ubuntu4.3~trusty1 amd64 X.Org X server -- Intel i8xx, i9xx display driver

You can see the prb is still here in attachment. Important note: I have Intel® HD Graphics 5500 announced as Broadwell GT2 by Ubuntu System Information, not GT3.

then the bugfix was never meant for you

It seems. I mark Bug #1432194 as duplicate as Chris told me it was the same bug as the current one. As some people may have the same different issue, what should I do? Create a new bug? De-depulicate #1432194 ? Thanks.

So what is the solution for all users with an Intel HD Graphics 5500 (GT2)? I'm also still having the problem on my Lenovo Thinkpad T450s

Is it possible to reopen the Bug #1432194 again? Is there a known upstream solution for this problem?

Unduped, that bug is probably a dupe of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1374389 instead

This bug was fixed in the package xserver-xorg-video-intel - 2:2.99.910-0ubuntu1.6

In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

tested the lts-utopic package on trusty, but since it's identical to the native utopic one marked this verified

It's unfortunate the utopic changelog didn't have the LP bug reference properly formatted.

utopic has 2:2.99.914-1~exp1ubuntu4.4 already
